Supramolecular interactions probed by 13C-13C solid-state NMR spectroscopy.
We present a robust solid-state NMR approach for the accurate determination of molecular interfaces in insoluble and noncrystalline protein-protein complexes. The method relies on the measurement of intermolecular (13)C-(13)C distances in mixtures of [1-(13)C]glucose- and [2-(13)C]glucose-labeled proteins. We have applied this method to Parkinson's disease-associated α-synuclein fibrils and fou...
متن کاملAccurate measurement of 13C-15N distances with solid-state NMR.
Solid-state NMR technique for measuring distances between heteronuclei in static powder samples is described. It is based on a two-dimensional single-echo scheme enhanced with adiabatic cross polarization. As an example, the results for intramolecular distances in alpha-crystalline form of glycine are presented. The measured NMR distances (13)C(alpha)-(15)N and (13)C(')-(15)N are 1.496+/-0.002 ...
متن کامل2H-DNP-enhanced 2H-13C solid-state NMR correlation spectroscopy.
Perdeuteration of biological macromolecules for magic angle spinning solid-state NMR spectroscopy can yield high-resolution (2)H-(13)C correlation spectra and the method is therefore of great interest for the structural biology community. Here we demonstrate that the combination of sample deuteration and dynamic nuclear polarization yields resolved (2)H-(13)C correlation spectra with a signal e...
متن کاملCharacterization of Stratum Corneum Molecular Dynamics by Natural-Abundance 13C Solid-State NMR
Despite the enormous potential for pharmaceutical applications, there is still a lack of understanding of the molecular details that can contribute to increased permeability of the stratum corneum (SC). To investigate the influence of hydration and heating on the SC, we record the natural-abundance (13)C signal of SC using polarization transfer solid-state NMR methods. Resonance lines from all ...
متن کاملTannin-Based Copolymer Resins: Synthesis and Characterization by Solid State 13C NMR and FT-IR Spectroscopy
In recent years, the interest for bio-sources is rising exponentially and tannins extracts are one of the most interesting, easily-available, phenolic building blocks. The condensed tannins or proanthocyanidins are already known for their polymerization chemistry, which is the basis for several natural-based materials (e.g., adhesives, foams). In the present work we aim to observe the behavior ...
